A weaker form of the same issue is reachable without an account and yields an arbitrary file write rather than code execution.","published":"2026-09-12T06:16:26.043","modified":"2026-09-12T06:16:26.043","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://wpscan.com/vulnerability/5ced30ea-8b78-495f-b10c-42b3f10adcb3/"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-12T06:16:26.043"}}
